I assembled my local store's black box hell pit yesterday and I've got to say that it is a great kit. It easily matches the plague furnace/screaming bell in height which is good and the model in real life is just as gribbly as the pictures make it out to be. Also it's less hard to build than you might think (I had to do it with no instructions so that's saying something!). Not a huge amount of spare parts when you're done but some of the spare arms could be grafted to a rat ogre or similar with a bit of green stuff. The hardest part was probably the multiple small heads that were around the main one as not all the heads fit in all the sections so it's worth doing a dry run with those before applying the glue. The kit's not exactly cheap but the scultping on the model is top quality (there are numerous little stichings which actually start on one piece and then 'hook' onto the piece where the stiching joins up, it's hard to describe but when you've built one you'll understand what I mean) and it certainly will be a centre piece for most skaven armies due to its sheer size.
